5-Bit or 6-Bit Programmable 2-,3-,4-Phase Synchronous Buck Controller

GENERAL DESCRIPTION The ADP3181 is a highly efficient multiphase synchronous buck-switching regulator controller optimized for converting a 12 V main supply into the core supply voltage required by high performance Intel processors. It uses an internal 6-bit DAC to read a voltage identification (

3V to 5.5V, 1.5Mbps RS-232 Receivers in SOT23-5

General Description The MAX3180–MAX3183 are single RS-232 receivers in a SOT23-5 package for space- and cost-constrained applications requiring minimal RS-232 communications. These devices minimize power and heat dissipation by consuming only 0.5µA supply current from a +3.0V to +5.5V supply volt
